PATENT-OFFICE WILLIAM G. WALLENBECK, or cnroneo, I LINoIs HOLDER FOR SAFETY RAZOR IBLAIDE S Application filed February 15, 1930. Serial No. 428,551.,

to manufacture'rand assembleand effective in use. An improvedfeature of my construction consists in providing the clamping members of the holderwitha pivotal support constructed entirely by punch] press operations and without the use ofa pivot rod, and a further purpose of my invention is to make use of a tubular handle having a readily removable inner frame which affords rigid support for the blade clamping members when in their blade holding position, this construction also affording the utmost of simplicity in assembling the device.

My invention will best be understood by reference to the accompanying drawing showing a preferred embodiment thereof, in

. which 7 Similar numerals refer to similar parts Fig. 1 shows my device'in' side elevation with a razor blade held thereby, Fig. 2 is an end view of the parts shown in Fig. 1, Fig. 3 is a S6CtlO112Ll' V1W to an enlarged scale, of the parts shown in-Figs. 1 and 2 taken along the line 3-3, v

throughout the several views. 7

I, Asshown in Figs. 1 and 2, my device consists of a tubular handle 10, which may, if desired, be formed from sheet metal, and when so formed, the joint between the edges of the blank is preferably in line with the parts projecting from? the handle. I The hana dle 10 contains a frame 11 which-is'a sliding fit in the handle,.an d the frame 11 has piv! oted thereto at 12, 12two clamping plates '13,

13 between which the razor blade 14 tofbe sharpened, may be held.' I I As shown in Figs. 3 andl to an enlarged scale, thefframe 11 consists of a strip of spring material bent at its midfportion' as indicated at 11a so that the two parts of the frame extend in substantially parallel relation to each otherwhen the frame is inserted in the handlelO. The. ends llb of the 'frame'have formed from them projections 11c, extending towards each other, which are 5 formed from the material of the frame by suitable tools, preferably in 'apunch press in connection with making the frame. The

projections 110 enter apertures 13a .in-the clamping plates 13 sothat when the device 0 is assembled, the plates 13 may be swung .pivotally on the projections, outwardly'from the handle to permit inserting and removing the razor blades between and from the clamping plates, as'desired. Adjacent the portion 11a of the frame, its substantially parallel portions are separated a distance equalsubk stantially to the combined thickness of the two plates 13 as aresult of which, when the plates are swung totheir clamping position indicated in Fig. 1, the inner edges of the. plates rest between these portions of the frame, which holdthe blades rigidly against lateral movement in the handle 10. ,The frame 11 is of strip material ofsucha width that when it is inserted injthe tubular handle 10, with the plates 13 between the walls of the frame, movement of the frame in the handle is prevented in all directions excepting longitudinally of the handle, and thus arigid support is afforded the plates .13 and the razorblade 1 f clamped between them, against the pressures exerted upon'the bladeYand plates during honing and stropping operav 9s tions V 1 As shown in Fig. 6, the handle 1O is'provided atone end, and preferably in line-with a the joint 10a. between the edges'of thesheet material forming the handle, assuming that itis made from a fiat sheet metal blank,

tively supports the razor blade for with a slot 10?) or substantially the length of the plates 13 and of a width substantially equal to the combined thickness of the two plates 13, so that swinging the two plates into the handle with a razor blade 14 between them, brings the edges of the slot 105 snugly into engagement with the plates. This, combined with the action of'the frame 11, posithe purvposes described.

13 are blanked and formedas shown in Fig. 5,, with pivot apertures 13a in them, the

:frame 11 is constructed'as shown in Fig; 4, the, two platesare placed together with their .pivot apertures 13a in line with each other and with th-eprojections 110 between which the plates are located, theendportions 117) of the frame '11 "are held together by the thumb and finger, with the projections 11a in the apertures 13a, and the frame and plates are pushed into the handle 10 -so that the plates will rest in the slot 10?). I find that the spring tensionrequiredto be exerted by the frame 11 on the parts for the purposes described, is no greater than canreadillybe overfcoine' by the pressure of .the thumb and finger in assembling the device, and that the resultant friction of the frame 11 in the handle 10 may readily 'beovercome manually in slipping the frame into the [handle with the plates 13 between the end portionsof the frame. When the device is assembled as described, the spring tension on the pivot portion'sof the frame; holds the plates in any position to which they maybe moved and also holds the Pi o projections llc in the pivot, pe res, 13a. y I i V v In Fig; 7 I show a modified construction inwhichthe'clamping plates 13?) have pivotal projections130 formed outwardly from them, preferably by suitable tools during the punching .and forming of the plates, and the frame 11d has pivot apertures 116 through its ends in line with land to receive the projection 130 the resulting pivotal construction being similar to thatshown'and described in connection with Figs. 3 and 4.-

In all other respects, theplates 13b and the frame- 'lldmay be ofthe same construction and have the same manner of assembly in the handle 10, and secure the same results asthe plates '13 and frame 11 respectively, the handle'lO being the same in either case. In this manner I not only aiford a positive support for the plates and razor bla.des,.but

I also provide a construction which after.

the several'parts are formed by means of simple punch press operations, no further machine operations of any kind .arerequired w in pivotally mounting the clamping plates in the handle, and furthermore the expense ofassembling the devic'eismuch less than where a further operation or operationsare In constructing and assemblingvthe device, the handle 10 is made as described, the plates I required in providing a separate pivot for the clamping plates, and with the marked advantage that the frame 11 which facilitates the assembling of the device, also affords a much more positive and rigid support for the clamping plates and the razor blades,

than is possible wherea separate pivot pin construction is relied upon to hold the plates 7 ping or honing. a

While I have shown my invention in the particular embodiment above described, it will be understood that I do'not limit myself to'th'is exact construction as I may employ equivalents knownto the art at. the time of and blades against movement under the pressures-exertedupon the blade during 'strop-i the filing of this application without departing from'the scope of'the appended claims.
